This question already has an answer here:
- Many parts in the bible where he said he can't do anything by himself, but by the will of God.
- If you look at the sentences above almost all the prophets before him used the same words.
- When he said son of God or my father, almost all prophets before him used the same word, because in some parts of the bible it mentions children of God. That means we are his brother and God is our father, I don't think that means we are really his children; it means we are servants and if we are servants, then Jesus too was a servant of God.
